Castlight Health Partners With Noom to Expand Access to Personalized Programs for Weight and Chronic Conditions

Castlight’s personalized health benefits platform provides seamless access to Noom’s health programs including diabetes, GLP-1s and weight support for employers and health plans.

SEATTLE and NEW YORK — December 8, 2025 — Castlight Health, the leading health navigation platform, and Noom, the leading platform for preventive health, today announced a new partnership to bring Noom’s program to Castlight’s extensive ecosystem of health and wellbeing partners.

Through this collaboration, employers can purchase Noom directly through Castlight, allowing members to seamlessly discover, access, and enroll in Noom programs – including Noom Weight, Noom Med, Noom Diabetes, and Noom Diabetes Prevention – directly through the Castlight app. Members also gain access to GLP-1s through Noom Med, helping those prescribed these medications integrate them effectively with lifestyle and behavior change for sustainable health outcomes.

Supported by Castlight’s personalized navigation and Care Guide services, members will receive timely nudges and recommendations that connect them with Noom’s psychology-based program to build healthier habits, achieve weight management and health goals, and improve long-term wellbeing.

“Weight management is one of the most urgent and costly challenges employers and health plans face today,” said Victor Leclere, SVP of Commercial at Castlight Health. “By embedding Noom into our ecosystem of 40+ partners — and powering it with Castlight’s proven ability to drive a 3.25x increase in engagement — we’re giving employers and health plans a smarter, more sustainable alternative to rising drug costs and a better way to support their members.”

Noom’s program leverages cognitive behavioral techniques, coaching, and technology to help users create sustainable lifestyle changes. By embedding into Castlight’s connected navigation platform, Noom will reach more individuals at critical moments in their health journey, removing barriers to discovery and making it easier for people to take action. The deep integration between Castlight and Noom helps incentivize members to complete micro-behaviors, linked to sustained engagement with the Noom program. Allowing employers to reward members for completing different activities, together, help members achieve long-term lifestyle changes aligned to their weight management goals. 

“At Noom, we believe small, science-backed changes can lead to lasting health improvements,” said Cody Fair, Noom’s Chief Commercial Officer. “Partnering with Castlight allows us to expand our reach and ensure that more employees and health plan members can benefit from our program, supported by Castlight’s proven navigation and engagement capabilities.”
